Cosmological Distance Measurement of 12 Nearby Supernovae IIP with ROTSE-IIIB
Govinda Dhungana, Robert Kehoe, Ryan Staten +14
We present cosmological analysis of 12 nearby () Type IIP supernovae (SNe IIP) observed with the ROTSE-IIIb telescope. To achieve precise photometry, we present a new image…
Dusty MgII Absorbers: Implications for the GRB/Quasar Incidence Discrepancy
Vladimir Sudilovsky, Donald Smith, Sandra Savaglio
There is nearly a factor of four difference in the number density of intervening MgII absorbers as determined from gamma-ray burst (GRB) and quasar lines of sight. We use a Monte-C…
Observations of Gamma-ray Bursts with the Rossi X-ray Timing Explorer
Hale Bradt, Alan M. Levine, Francis E. Marshall +3
The role of the Rossi X-ray Timing Explorer (RXTE) in the study of Gamma-ray Bursts (GRBs) is reviewed. Through April 2001, the All-Sky Monitor (ASM) and the Proportional Counter A…
A Search for Early Optical Emission from Short and Long Duration Gamma-ray Bursts
Robert Kehoe, Carl Akerlof, Richard Balsano +16
Gamma-ray bursts of short duration may harbor vital clues to the range of phenomena producing bursts. However, recent progress from the observation of optical counterparts has not…
Evidence for a Sudden Magnetic Field Reconfiguration in SGR 1900+14
Peter M. Woods, Chryssa Kouveliotou, Ersin Gogus +5
We report the detection of large flux changes in the persistent X-ray flux of SGR 1900+14 during its burst active episode in 1998. Most notably, we find a factor ~700 increase in t…
X-ray Transients Monitored by the All-Sky Monitor on RXTE: A Tabulation
Hale Bradt, Alan Levine, Ronald Remillard +1
We present a tabulation of 46 transient x-ray sources monitored with the All-Sky Monitor (ASM) on the Rossi X-ray Timing Explorer (RXTE). They fall into four broad categories: shor…
Transient X--Ray Sources Observed with the Rxte All-Sky Monitor after 3.5 Years
Hale Bradt, Alan M. Levine, Ronald A. Remillard +1
We present light curves of a sample of "transient" sources observed with the All-Sky Monitor (ASM) of the Rossi X-ray Timing Explorer (RXTE). The light curves extend over 3.5 years…
Gamma-ray Burst Positions from the ASM on RXTE
Hale V. Bradt, Donald A. Smith
The RXTE/ASM has detected and positioned 14 confirmed GRB bursts (at this writing, Jan. 1999) including six whose positions were comunicated to the community 2 to 32 hours after th…
RXTE All-Sky Monitor Localization of SGR 1627-41
Donald A. Smith, Hale V. Bradt, Alan M. Levine
The fourth unambiguously identified Soft Gamma Repeater (SGR), SGR1627-41, was discovered with the BATSE instrument on 1998 June 15 (Kouveliotou et al. 1998). Interplanetary Networ…
RXTE Discovery of Coherent Millisecond Pulsations during an X-ray Burst from KS 1731-260
Donald A. Smith, Edward H. Morgan, Hale Bradt
A highly coherent 523.92+-0.05 Hz periodic X-ray signal has been observed during a type I X-ray burst from the low-mass X-ray binary system KS 1731-260 with the PCA on RXTE. The sp…
First Results from the All-Sky Monitor on the Rossi X-ray Timing Explorer
Alan M. Levine, Hale Bradt, Wei Cui +5
The All-Sky Monitor on the Rossi X-ray Timing Explorer has been monitoring the sky in the 1.5 - 12 keV band since late February. The instrument consists of three coded-aperture cam…
